I found twoboardsinside,tightly connected to each other by a pad of twenty jumpers.
One board with a multiplexer and a processor, and the other with a Bluetooth module and power system. And yes, there is a USB connector; it’s like oldLaunch EasyDiag.
There are the following markings on the Launch M-Diag Lite main (processor) board :
LAUNCH 10200716
DBSCAR_MAIN_STM32F207 – name of the board and the processor used
2015.05.29 – production date
V1.00.000 – version of the board
On the “communication” board there are the following markings:
102200685
V1.00.000 – version of the board
It’s kind of different from the version 2014.11.08 (production date)
The main board has:
Processor STM32F207IGH6
Multiplexer JV700
Also on the board contacts are similar to the connection of the service connector.
The communication board uses only two controllers in the Bluetooth module:
